Hello my name is ***** ***** I will assist you. Yes most probably it is the fuel system. Start by checking the fuel tank, for any blockages, move all the way with the line and fuel filter up to the engine making sure there is no blockages. Check also the filter inside the engine as well. If everything is clean then what i suggest you do is to remove the carbs and get them cleaned and rebuilt.
Try the above and let me know. If you need further assistance feel free to post back.
